About the B94 Code Range
The ICD-10 code B94 covers the sequelae, or long-term complications, following various infectious and parasitic diseases. These codes are used to document the aftereffects experienced once the initial infection has resolved but has left residual health issues.
Specifically, B94.0 identifies sequelae of trachoma, which may be noted as lasting conditions following infection by Chlamydia. For viral infections, B94.1 and B94.2 capture sequelae of viral encephalitis and viral hepatitis, respectively, also referred to as late effects of these diseases. The code B94.8 is a broader category used for sequelae of other specified infectious and parasitic diseases, including diverse conditions such as postherpetic scars, arthritis following infections, or post-infectious glomerulonephritis. Lastly, B94.9 includes sequelae from unspecified infectious or parasitic diseases, used when the precise infection is unknown but ongoing complications persist, like postinfectious neuralgia or post-viral depression. These codes help medical coders accurately report the continuing health impact related to prior infections for proper patient management and insurance purposes.
